Variables and Constant

Constants and variables are widely used in mathematical equations and expressions. They are also commonly found in the domain of programming, where each language has its own way to differentiate between a constant and a variable. Since they have all sorts of applications, knowing their differences is a good place to start.

uppose you have a certain amount of money in a savings account that earns compoundmonthly interest, and you want to calculate the amount that you will have after a specificnumber of months. The formula, which is known as the future value formula, is:F=P×(1+i)tThe terms in the formula are as follows:o F is the future value of the account after the specified time period.o P is the present value of the account.o i is the monthly interest rate.o t is the number of months.Write a program that prompts the user to enter the account’s present value, monthlyinterest rate, and the number of months that the money will be left in the account. Theprogram should pass these values to a function named futureValue that returns thefuture value of the account, after the specified number of months. The program shoulddisplay the account’s future value. i attached the screenshot of the output so the output should look like that. the coding should be in c++

Q1: The local Driver's License Office has asked you to write a program that grades the writ- ten portion of the driver's license exam. The exam has 20 multiple choice questions. Here are the correct answers: 1. A 2. D 3. B 4. B 5. C 6. B 7. A 8. B 9. C 10. D 11. A 12. C 13. D 14. B 15. D 16. C 17. C 18. A 19. D 20. B Your program should store the correct answers shown above in an array. It should ask the user to enter the student's answers for each of the 20 questions, and the answers should be stored in another array. After the student's answers have been entered, the program should display a message indicating whether the student passed or failed the exam. (A student must correctly answer 15 of the 20 questions to pass the exam.) It should then display the total number of correctly answered questions, the total number of incorrectly answered questions, and a list showing the question numbers of the incorrectly answered questions.

7) The ideal gas law allows the calculation of volume of a gas given the pressure(P), amount ofthe gas (n), and the temperature (T). The equation is:V = nRT / PSince we only have used integer arithmetic, all numbers will be integer values with nodecimal points. The constant R is 8.314 and will be specified as (8314/1000). This givesthe same result. Implement the idea gas law program where the user is prompted for andenters values for n, T, and P, and V is calculated and printed out. Be careful toimplement an accurate version of this program. Your program should include a properand useful prompt for input, and print the results in a meaningful manner
The Nim game. Write a program for a two-player version of the game Nim: a human player will play against the computer. The game is simple: players take turns removing from 1 to 4 sticks from a pile of 13 sticks; the player who picks up the last stick wins the game. Here’s some pseudocode for the Nim game. Start by initializing some variables that will allow you to keep track of the state of the game: One variable should record how many sticks there are left in the pile; initially, this variable must be initialized to 13. There are two players in the game, who take turns. To remember who’s turn is next, use a variable with two states (= values). Say the variable is 1 if the human player is next, and it is 2, if the computer’s turn is next. Pick randomly the player who should start the game. Then, start the main loop of the game: the game should continue for as long as there still are sticks (at least one) to pick. In each repetition of the game loop, one player will play their turn:…
A retail company assigns a $5000 store bonus if monthly sales are $100,000 or more. Additionally, if their sales exceed 125% or more of their monthly goal of $90,000, then all employees will receive a message stating that they will get a day off. Step 3: Complete the pseudocode by writing the missing lines. When writing your modules and making calls, be sure to pass necessary variables as arguments and accept them as reference parameters if they need to be modified in the module. (Reference: Writing a Decision Structure in Pseudocode, page 118). Module main () //Declare local variables Declare Real monthlySales //Function calls Call getSales(monthlySales) ______________________________________________________ ______________________________________________________ End Module //this module takes in the required user input Module getSales(Real Ref monthlySales) Display “Enter the total sales for…
